chirpy Posted July 14, 2010 Share Posted July 14, 2010 hi,I remember reading somewhere advice re using equipment such as a Karcher to wash cars.Especially possible damage to electrics if water gets throgh any gaps in the bonnet.Any advice?

DavyH Posted July 14, 2010 Share Posted July 14, 2010 I've been cleaning my cars with a high pressure cleaner for years, never had a problem. Have a can of WD40 ready if you think water may get into your electrics! Link to comment Share on other sites More sharing options...
Théière Posted July 14, 2010 Share Posted July 14, 2010 The water jet by itself loosens mud, crud, etc but can still leave a film on the car. Much better to use the rotating brush attachment which will prevent that happening anyway. Link to comment Share on other sites More sharing options...
Polly Posted July 14, 2010 Share Posted July 14, 2010 Washing your car frequently is another solution, then the crud doesn't build up and a simple hose with a jet nozzle will get it clean Link to comment Share on other sites More sharing options...
AnOther Posted July 14, 2010 Share Posted July 14, 2010 With the bonnet closed you're unlikely to get water under it in sufficient quantities or pressures to do any harm but nevertheless jet washes should be used with common sense. The indiscriminate application of water jets at anything up to 2000psi can easily force water into crevices and cavitites it would never ever get into in normal use where it can cause damage to things like door electrics and also be a long term source of moisture which will encourage corrosion.A simple way to minimise the chances of this is to wash from front to back only aiming the jet in the direction that any natural water would strike the car.Frankly, however dirty a car gets. it's very unlikely to be anything that can't be coped with by hand washing and a standard hosepipe and jet washing is nothing more than the lazy persons quick fix solution !

AnOther Posted July 14, 2010 Share Posted July 14, 2010 I think for the vast majority we would be talking about jet washing private cars not a commercial vehicle which presumably works for its living where time is money [;-)] Link to comment Share on other sites More sharing options...
Beemer1150 Posted July 14, 2010 Share Posted July 14, 2010 ...and when you live the wrong side of a farm full of vache a jet washer is by far the best way of getting the resulting 'mud' out from under the wheel arches.Not lazy at all, just the most thorough way of getting ride of the corrosive stuff.

Chancer Posted July 14, 2010 Share Posted July 14, 2010 Once a year through the £1.99 tesco car wash whether she needs it or not!It does help to have a silver car, be partially sighted and not give a flying **** any more about how shiny your bagnole is.

Jonzjob Posted July 16, 2010 Share Posted July 16, 2010 Slightly off topic, but still with pressure washers. It is a very bad idea to pressure wash a caravan because the high pressure water can and will force the non setting mastic from the joints in the bodywork. Then you have the perfect situation for the caravan killer, damp!You got a 2CV Polly?[8-)] If so then I am envious!! I want a Méhari!

nomoss Posted July 19, 2010 Share Posted July 19, 2010 I once had my Land Rover high pressure washed after an excursion in deep mud in the jungle.I later found that a significant amount of muddy water had been forced past the rubber seals into both axles and the front swivel hubs.
